1. Transition of Power: Delhi Sultanate to Mughals (basic)
The early 16th century marked a definitive turning point in Indian history, transitioning from the decentralized rule of the Delhi Sultanate to the centralized authority of the Mughal Empire. By 1526, the Delhi Sultanate, under the
Lodi Dynasty, was struggling with internal fractures and noble rebellions.
Zahiruddin Muhammad Babur, a descendant of both Timur and Genghis Khan, seized this opportunity. At the
First Battle of Panipat (1526), Babur’s use of innovative military tactics—specifically
artillery (Tulughma) and gunpowder—allowed his smaller army to crush the massive forces of
Ibrahim Lodi. This victory did not just replace one king with another; it signaled the end of the Sultanate era and the birth of the
Mughal Empire Rajiv Ahir, A Brief History of Modern India, India on the Eve of British Conquest, p.61.
While the Mughals were establishing their roots in the North, the Indian peninsula was far from a political vacuum. In Southern India, the
Vijayanagara Empire was at its absolute zenith under
Krishna Deva Raya (1509–1529) of the Tuluva dynasty
History Class XI (Tamilnadu State Board), Bahmani and Vijayanagar Kingdoms, p.181. He was a contemporary of Babur, and the two empires represented the dominant powers of their respective halves of the subcontinent. Babur was so impressed by the strength of the Southern empire that in his autobiography, the
Baburnama, he explicitly named Krishna Deva Raya as the most powerful ruler in India during that period
History Class XII (NCERT), An Imperial Capital: Vijayanagara, p.173.
1509 — Krishna Deva Raya ascends the throne of Vijayanagara.
1526 — First Battle of Panipat: Babur defeats Ibrahim Lodi.
1529 — Death of Krishna Deva Raya; end of the Vijayanagara peak.
Key Takeaway The transition from the Delhi Sultanate to the Mughals was facilitated by superior military technology (artillery) and occurred while the Vijayanagara Empire was at its peak under Krishna Deva Raya.

2. Chronology of Vijayanagara: The Four Dynasties (basic)
The Vijayanagara Empire, founded in 1336, was not ruled by a single continuous lineage but by four distinct dynasties that shaped the political landscape of South India for over three centuries. According to tradition and historical inscriptions, the empire was established by two brothers, Harihara and Bukka, who were initially in the service of the Hoysala rulers before asserting their independence History, Class XI (Tamilnadu State Board), Chapter 12, p.180. This foundation occurred during a period of political flux in the Deccan, specifically following the decline of the Hoysalas and the expansionist pressures from the Delhi Sultanate.
To master the chronology of Vijayanagara, one must visualize the transition of power through these four stages:
1336–1485: Sangama Dynasty — Founded by Harihara I. This was the longest-ruling dynasty and focused on consolidating territory against the Bahmani Sultanate.
1485–1505: Saluva Dynasty — A relatively short-lived period established by Saluva Narasimha, who took control to prevent the empire's collapse due to internal rebellion.
1505–1570: Tuluva Dynasty — Considered the "Golden Age," particularly under Krishna Deva Raya. It was during this era that the empire reached its military and cultural zenith THEMES IN INDIAN HISTORY PART II, History CLASS XII, Chapter 7, p.171.
1570–1650s: Aravidu Dynasty — Established by Tirumala (brother of Rama Raya) after the disastrous Battle of Talikota (1565). The capital shifted from Vijayanagara to Penugonda and later Chandragiri as the empire's power gradually waned History, Class XI (Tamilnadu State Board), Chapter 12, p.183.
Understanding this sequence is vital because each dynasty responded to different external threats—from the initial struggle for survival (Sangama) to the peak of imperial glory (Tuluva) and the eventual defensive decentralization (Aravidu). While the ruling families changed, the administrative structure and the title of 'Raya' remained a symbol of authority across all four periods.
Remember: S-S-T-A
Sangama → Saluva → Tuluva → Aravidu
(Think: Some Scholars Teach Art)
Key Takeaway The Vijayanagara Empire was governed by four successive dynasties—Sangama, Saluva, Tuluva, and Aravidu—moving from foundation (1336) to its peak under the Tuluvas and eventual decline post-1565.

3. Geopolitical Conflicts: Raichur Doab and Bahmani Kingdom (intermediate)
To understand the medieval history of the Deccan, we must first look at the map. A 'Doab' (literally 'two waters') is the fertile land situated between two converging rivers. The Raichur Doab, nestled between the Krishna and Tungabhadra rivers, became the most contested piece of real estate in South India for over two centuries. This region was not just a prize for its agricultural wealth; it was a strategic buffer zone between the Vijayanagara Empire to the south and the Bahmani Sultanate to the north History , class XI (Tamilnadu state board 2024 ed.), Chapter 12, p.176.
The rivalry began almost immediately after the founding of these two powers in the mid-14th century. For the Bahmani rulers, starting with Alauddin Bahman Shah, the Doab was essential for securing their southern frontier and funding their military. To manage these constant campaigns and govern his expanding realm, Bahman Shah divided his kingdom into four administrative units called tarafs, each led by a governor History , class XI (Tamilnadu state board 2024 ed.), Chapter 12, p.176. However, these endemic wars over the Raichur Doab were a double-edged sword; while they led to territorial gains, they also significantly exhausted the financial resources of both kingdoms over time History , class XI (Tamilnadu state board 2024 ed.), Chapter 12, p.187.
As we move through the timeline, the nature of this conflict evolved. While we often view these powers as permanent enemies, there were long periods where they sought a delicate balance of power. Interestingly, the Vijayanagara kings often tried to ensure the stability of the Sultanates to prevent any single power from becoming too dominant. It was only much later, when the Bahmani Sultanate split into five successor states (Bijapur, Ahmednagar, Berar, Bidar, and Golconda), that the political game changed. The Vijayanagara ruler Rama Raya attempted an 'adventurous policy' of playing these Sultanates against one another, which eventually backfired and led to the decisive downfall of Vijayanagara at the Battle of Talikota THEMES IN INDIAN HISTORY PART II, History CLASS XII (NCERT 2025 ed.), Chapter 7, p.174.
Key Takeaway The Raichur Doab (between the Krishna and Tungabhadra rivers) was the primary economic and strategic flashpoint that defined the two-hundred-year rivalry between the Vijayanagara Empire and the Bahmani Sultanate.

4. The Deccan Sultanates: Successors of the Bahmanis (intermediate)
The story of the Deccan Sultanates is a fascinating chapter of fragmentation and shifting alliances. Following the decline of the Bahmani Kingdom—which had originally been divided into four administrative units called tarafs—a series of weak successors to Sultan Mohammed III led to the empire splintering into five independent kingdoms History , class XI (Tamilnadu state board 2024 ed.), Bahmani and Vijayanagar Kingdoms, p.176. These states, collectively known as the Deccan Sultanates, emerged between 1490 and 1512, each ruled by a distinct dynasty. While they were often at each other's throats, they shared a common geopolitical rival: the Vijayanagara Empire to the south.
To keep these five sultanates straight, it helps to look at them through their dynastic lenses:
| Sultanate |
Dynasty |
Fate/Significant Fact |
| Bijapur |
Adil Shahi |
Eventually annexed Berar and Bidar; conquered by Aurangzeb in 1686. |
| Ahmadnagar |
Nizam Shahi |
A major player in the Talikota alliance; later absorbed by the Mughals. |
| Golkonda |
Qutb Shahi |
Famous for the Golkonda Fort and diamond trade; conquered by Aurangzeb in 1687. |
| Berar |
Imad Shahi |
The first to secede but the first to be annexed (by Ahmadnagar). |
| Bidar |
Barid Shahi |
The smallest sultanate; where the last Bahmani puppets resided History , class XI (Tamilnadu state board 2024 ed.), Bahmani and Vijayanagar Kingdoms, p.179. |
The defining moment for these sultanates occurred in 1565 at the Battle of Talikota (also known as Rakshasi-Tangadi). For centuries, the Bahmanis and Vijayanagara had fought over the fertile Raichur Doab—the land between the Krishna and Tungabhadra rivers History , class XI (Tamilnadu state board 2024 ed.), Bahmani and Vijayanagar Kingdoms, p.187. In a rare display of unity, the sultanates of Bijapur, Ahmadnagar, and Golkonda formed a grand alliance to defeat Rama Raya, the chief minister of Vijayanagara. The city was sacked and eventually abandoned, marking the beginning of the end for the great southern empire THEMES IN INDIAN HISTORY PART II, History CLASS XII (NCERT 2025 ed.), An Imperial Capital: Vijayanagara, p.173.
Ultimately, these sultanates could not withstand the southward expansion of the Mughal Empire. By the late 17th century, under the reign of Aurangzeb, the remaining powerful states of Bijapur and Golkonda were finally annexed, ending the era of Deccani independence History , class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.211.
1490–1512 — Breakup of Bahmani Sultanate into five independent states.
1565 — Battle of Talikota: Sultanate alliance defeats Vijayanagara.
1686–1687 — Aurangzeb conquers Bijapur and Golkonda, ending the sultanates.
Key Takeaway The Deccan Sultanates emerged from the ruins of the Bahmani Kingdom and are best remembered for their 1565 alliance that crippled the Vijayanagara Empire at the Battle of Talikota.

5. Foreign Travelers and Literary Sources of the 16th Century (exam-level)
The 16th century marks a fascinating intersection in Indian history where the North witnessed the birth of the Mughal Empire while the South saw the Vijayanagara Empire reach its absolute zenith. When Babur invaded India in 1526, he recorded in his autobiography, the Baburnama, that the most powerful ruler in India at that time was not a Sultan of Delhi, but Krishna Deva Raya (reigned 1509–1529) of the Tuluva dynasty THEMES IN INDIAN HISTORY PART II, Chapter 7, p.173. This recognition highlights how political power was balanced across the subcontinent during this era.
Krishna Deva Raya’s reign was defined by both military expansion and a "Golden Age" of literature. He successfully acquired the fertile Raichur doab in 1512 and inflicted a major defeat on the Sultan of Bijapur in 1520 THEMES IN INDIAN HISTORY PART II, Chapter 7, p.173. Culturally, he was a polyglot and a scholar, earning the title Andhra Pitamaha. His court was graced by the Ashtadiggajas (eight great poets), including Tenali Rama. He himself authored Amuktamalyada in Telugu and Sanskrit works like Jambavati Kalyanam History, class XI (Tamilnadu state board 2024 ed.), Chapter 12, p.186.
To reconstruct this period, historians rely heavily on foreign travelers, particularly the Portuguese, who sought trade alliances and horses. It is vital to distinguish between the travelers of the 15th and 16th centuries to maintain chronological accuracy:
| Period |
Notable Travelers |
Origin |
| 15th Century |
Nicolo de Conti, Abdur Razzaq, Afanasii Nikitin |
Italy, Persia, Russia |
| 16th Century |
Duarte Barbosa, Domingo Paes, Fernao Nuniz |
Portugal |
Domingo Paes, visiting during Krishna Deva Raya's time, famously described the capital city as being as large as Rome and filled with groves, gardens, and beautiful conduits of water Exploring Society: India and Beyond, Class VIII, Chapter 2, p.35. These accounts provide an outsider's perspective on the immense wealth and administrative efficiency of the Tuluva rulers before the empire began its slow decline under later rulers like Sadasiva Raya.
1509–1529 — Reign of Krishna Deva Raya (Peak of Tuluva Dynasty)
1512 — Acquisition of the Raichur Doab
1520 — Defeat of the Sultan of Bijapur
1526 — Babur establishes Mughal rule; mentions KDR in Baburnama
Key Takeaway The 16th century was a period of "Imperial Consolidation" where the Tuluva dynasty under Krishna Deva Raya dominated the South, a fact acknowledged by the Mughal founder Babur and detailed by Portuguese chroniclers like Domingo Paes.

6. The Golden Age under Krishna Deva Raya (1509–1529) (exam-level)
To understand the peak of the Vijayanagara Empire, we must focus on the reign of
Krishna Deva Raya (1509–1529). He belonged to the
Tuluva dynasty, the third of the four dynasties that ruled the empire. His era is often described as the 'Golden Age' because he moved beyond mere survival against the Deccan Sultanates to a period of total
expansion and consolidation. He wasn't just a warrior; he was a statesman who understood that controlling resources was the key to power.
Themes in Indian History Part II, Chapter 7, p.173
His military record is a masterclass in regional strategy. In 1512, he successfully acquired the Raichur Doab, the incredibly fertile land nestled between the Krishna and Tungabhadra rivers. This region was the 'breadbasket' of the Deccan and a primary cause of conflict for centuries. By 1514, he had subdued the Gajapati rulers of Orissa, and in 1520, he inflicted a crushing defeat on the Sultan of Bijapur. To cement his eastern victories, he famously erected a pillar of victory at Simhachalam. History, Class XI (Tamilnadu State Board), Chapter 12, p.181-182
What makes Krishna Deva Raya a central figure in medieval political chronology is his place in the broader Indian context. He was a contemporary of the first Mughal Emperor, Babur. Interestingly, in his autobiography, the Baburnama, Babur identifies Krishna Deva Raya as the most powerful ruler in India during the time of the Mughal invasion (1526). He also managed complex foreign relations, maintaining a strategic alliance with the Portuguese. By providing them permission to build a fort at Bhatkal, he secured a steady supply of high-quality Arabian horses, which gave his cavalry a significant edge over his rivals. History, Class XI (Tamilnadu State Board), Chapter 12, p.182
1336–1485 — Sangama Dynasty (Founders)
1485–1505 — Saluva Dynasty (Military commanders take over)
1505–1570 — Tuluva Dynasty (Peak under Krishna Deva Raya)
1570–1650 — Aravidu Dynasty (Post-Talikota decline)
Remember KDR was the Top of the Tuluvas. He ruled when Babur arrived!
Key Takeaway Krishna Deva Raya (1509–1529) of the Tuluva dynasty marked the empire's military and political zenith, famously recognized by Babur as India's most powerful king.

7. Solving the Original PYQ (exam-level)
Now that you have mastered the timelines of the Delhi Sultanate and the rise of the Vijayanagara Empire, this question asks you to synchronize North and South Indian history. This is a classic UPSC approach: testing whether you can connect the building blocks of different regions into a single chronological map. To solve this, you must anchor your reasoning to a pivotal date: 1526, the year Babur defeated Ibrahim Lodi at the First Battle of Panipat. By identifying the ruler in the South during this specific window (the early 16th century), you bring together your knowledge of the Mughal advent and the Tuluva dynasty's peak.
To arrive at Krishna Deva Raya as the correct answer, look for the contemporary ruler who defined the apogee of Vijayanagara power. As highlighted in THEMES IN INDIAN HISTORY PART II (NCERT), his reign (1509–1529) perfectly overlaps with Babur's invasion. An essential logical cue is provided by Babur himself; in his autobiography, the Baburnama, he explicitly names Krishna Deva Raya as the most powerful king in India. This primary source connection confirms that while Babur was establishing the Mughal Empire in the North, the South was under its most iconic sovereign.
UPSC frequently uses chronological displacement as a trap. Options like Devaraya II (1422–1446) and Saluva Narasimha (1485–1491) are wrong because they ruled during the 15th century, long before the Mughals arrived. On the other hand, Sadasiva Raya (1542–1570) represents the empire's later phase leading toward the Battle of Talikota. By maintaining a clear mental timeline and using 1526 as your "anchor year," you can easily filter out these earlier and later rulers to select the correct contemporary.
